The title basically explains it all; I would like to know about projectors. I want to start working on larger canvases and I am looking into various image transfer methods. I initially looked into projectors first, but when I looked around on various online retail sites (Dick Blick, Cheap Joe's, etc.) there seemed to be mixed reviews on how well most, if not all, projectors performed. I don't really feel like spending a fairly large amount of money on something and then not having it work as I would need it to. I suppose that my questions would be...
Do you use a projector frequently when doing paintings? Which one do you use and/or recommend? What are the upsides and downsides that you experience when using a projector?
If you do NOT use a projector, then what method do you personally use for transferring small images onto larger canvases? What method do you prefer and why? Why did you shy away from using a projector?
Writing this close to my bedtime, so thanks in advance.
